A post in "Cancelled Airliners" a few minutes ago made me think of a question I have about the proposed 727-300.

I have read about this proposed aircraft numerous times. I understand that it included a 220 inch stretch over a 727-200 and revised landing gear. I have never seen a single drawing or sketch of the proposed (and ulitimatelt cancelled) aircraft.

Does anyone know if such a drawing or sketch exists?

I seem to recall a drawing/artist's impression....possibly in Flight Intl magazine around 1977/78 when it was proposed.

If memory serves, only UA showed interest.




Panam, TWA, Ansett, Eastern.......AC next? Might be good for Canada.

Boeing dropped any plans for such an airliner after they gave the go-ahead for the then-new and similarily sized B757-200.

Thankfully Boeing wisely went with a new airframe instead of another stretch in this instance. Can you imagine the amount of runway a stretched -200 would require to takeoff?

The Boeing 727-300 was a projected 220 inch stretch of the basic 727-200 with a modified wing, new four-wheel main undercarriage trucks, and wide fan JT8D-217 engines. The wing included 747-style leading edge flaps outboard, conventional slat section inboard, and a much simpler system of double-slotted (as opposed to triple-slotted) trailing edge flaps. The wing span was to be increased by 60 inches and the tailplane span by 40 inches. The aircraft was designed to carry 220 tourist-class passengers over a 2000 mile stage-length, with 10% better seat mile costs than the 200-series. The -300 project was cancelled in 1975, when Boeing's attention switched to a project that was later to become the 757, known as the 7N7 during devolopment and pictured below.

Thanks Starship..

That's just what I was looking for. That Eastern 7N7 is a beautiful aircraft.

If memory serves, the Boeing concept plane listed above was referred to as the 7J7, not the 7N7.

Just my .02 worth.  Smile

No, it was indeed called the 7N7.

The 7J7 was a small widebody with the UDF (unducted fan) engine.

I didn't know the 757 was originally designed as a T-tail. I thought that the 727-300 was changed, and it became the 757-200. That's interesting!

Guess I'm wrong!

Notice the original 757 concept also had a 707/727/737 style nose/cockpit.

Boeing had been considering the 727-300 but world economics and the impending arrival of the 757 meant that the aircraft was never built.

Actually, during the 1976-1978 time frame Boeing offered a lengthened 727 variant that would have been powered by two PW2037 engines instead of three JT8D engines. There was actually interest from several major 727 users in the USA over this proposal, but after running some numbers in regards to economics of the 727 updated design Boeing decided to build an all-new plane instead--the 757-200. Now you know why airlines with very large 727-200 fleets in the 1970's (AA, CO, DL, NW and UA) all eventually bought the 752.

Look closely Twa902fly, it says 727 on the side.
